Starting this discussion thread because this drama includes classical music pieces that some people, like me, are finding difficult to find information about. I thought it would be helpful to have a place where we can discuss them—not just to understand the technical aspects of the pieces, but also to understand the depth of the characters and why a particular piece of music was chosen at a particular moment to add another layer to the story.

Found this helpful reddit post regarding this although the accuracy is what I am not sure of here.
